java Map 迭代key,value 最简洁的方法

import java.util.HashMap;

import java.util.Map;

public class EntrySets {

    public static void main(String[] args) {

        Map<Object, Object> map = new HashMap<Object, Object>();

        map.put("k1", "v1");

        map.put("k2", "v2");

        getItem(map);

    }

    static void getItem(Map map) {

        map.forEach((key, value) -> print(key + ":" + value));

    }

    static void iterByKey(Map map) {

        /**  iter map  by key */

        for (Object k : map.keySet()) {

            String v = map.get(k).toString();

        }

    }

    static void print(Object o) {

        System.out.println(o);

    }

}
